Notfälle bei extrapyramidalen Erkrankungen

Zusammenfassung Extrapyramidalen Störungen liegen zwar meist chronische Erkrankungen zugrunde, jedoch kommt es unter Umständen auch zum akuten Auftreten oder zu einer dramatischen Verschlechterung bis hin zu lebensbedrohlichen Zuständen. So kann ein Infekt, Medikamentenentzug oder eine Exikkose bei Parkinson-Patienten eine akinetische Krise auslösen. Auch akute, therapieassoziierte Psychosen mit Halluzinationen, Verwirrtheits- und Unruhezuständen können beim Parkinson-Patienten eine Notfallbehandlung erforderlich machen. Akute medikamenteninduzierte Dystonien treten nach einer Latenz von Stunden bis Tagen nach der Therapie mit Neuroleptika auf. Diese Frühdyskinesien können mit i.v.-Gabe von Anticholinergika effektiv behandelt werden. Seltene Folge einer Neuroleptikatherapie ist das maligne neuroleptische Syndrom, das mit Hyperthermie, Rigor und Bewusstseinsveränderungen einhergeht und zur kardiopulmonalen Dekompensation führen kann. Auch hier ist eine rasche Diagnosestellung entscheidend.     

Methods of Measuring Community Characteristics

There is increasing interest in the influence of community characteristics on child development and family functioning. In order to address questions on community influence, it is important to be aware of the measures available and their strengths and limitations. Useful strategies have been developed within a number of disciplines, including sociology, social and community psychology, and criminology. Methods include summarising information from existing administrative databases and census data, conducting observations, and using survey instruments with residents. The most commonly used methods are reviewed and their psychometric properties described .     

Activation of guinea pig eosinophil respiratory burst by leukotriene B4: role of protein kinase C

Leukotriene B4 (LTB4) and the protein kinase C activator, 4-beta-phorbol dibutyrate (PDBu), both induced a pronounced and concentration-dependent stimulation of hydrogen peroxide (H2O2) generation by purified guinea pig peritoneal eosinophils in the concentration range 1 nM-1 microM. The LTB4 response was inhibited competitively by the specific LTB4 receptor antagonist, U-75302, with a KB of 25 nM, while the concentration-response curves for both stimuli were shifted rightwards (3.8-fold and 2.8-fold for LTB4 and PDBu, respectively) by the competitive protein kinase C inhibitor, 1-O-hexadecyl-2-O-methylglycerol at a concentration of 300 microM. LTB4 appears, therefore, to induce respiratory burst in eosinophils via a receptor-mediated mechanism involving protein kinase C.     

Schlaganfallverbund Essen

Modern stroke care is now comparable to the care for cardiac ischemia. Although there are 100 stroke units in Germany, only a few patients can be treated with all the options available with evidence-based medicine. The stroke network in Essen is based on a concept, which optimizes all elements of stroke care, from the acute onset to rehabilitation. The Essen manual on stroke summarizes all results of the local round table talks. Logistics for acute situations, recommendations for prehospital care, and requirements at admission are explained in detail. With networks for stroke, patient care can be optimized and costs can be saved.

Morbidität nach Herztransplantation

The morbidity in the long-term course following heart transplantation in childhood is mainly determined by the morbidity of the transplanted graft, by side effects caused by immunosuppression and by psychosocial morbidity due to the special situation of life and growing up with a transplanted heart. Transplant vasculopathy as a specific disease of the transplanted organ itself, is a common complication following heart transplantation and is an important factor of morbidity and mortality, considerably limiting the long-term prognosis. Progressive disturbance of renal function and cumulative incidence of malignant tumors is a further factor limiting prognosis caused by the side effects of immunosuppression.     

Benign extracerebral fluid collections: a cause of macrocrania in infancy

In order to determine the frequency and natural history of benign extracerebral fluid collections, computed tomography reports from a period of 26 months at Oklahoma Children's Memorial Hospital were reviewed (total scans: 3,411). Bilateral frontal extracerebral fluid collections were found in 94 infants under 1 year of age. Eighty-two infants had computed tomography scans as part of the evaluation for macrocrania. Thirteen patients had the typical findings of benign extracerebral fluid collections but otherwise were completely asymptomatic. Longitudinal observation for up to 30 months failed to reveal any changes in neurologic status of these patients. Benign extracerebral fluid collections are a relatively common cause of macrocrania in infants. The presence of these fluid collections is not of immediate concern, providing that clinical evaluations fail to identify either neurologic or developmental abnormalities.
